Ice Maker

Ice Maker is a machine that freezes water into ice. It will relocate the heat energy from the water until the water is -20 °C ice. The ice maker heats up significantly but the total heat output is negative 3700 DTU/second. The DTU deleted per second does not change depending on the input water temperature though hotter water will take longer to become ice.

It will start new production cycles as long as there is less than 150 kg of ice in storage for a theoretical storage capacity of 179.9 kg.

The Ice Maker used to have no overheat temperature, so it could be used to achieve high temperatures. However, this has been addressed in a patch for the Automation Update, and it now has an overheat temperature. The only building without one now is the kiln.

Heat deletion:
It cools the 30 kg of stored water at a rate of around 0.16 K/s and consumes 60 W. This translates to a cooling efficiency of 333.33 DTU/W. In comparison, the Thermo Aquatuner would cool 10 kg of water at 14 K/s and consume 1200 W, an efficiency of 487.43 DTU/W. Note that the Ice maker does not respect the usual hysteresis of water's freezing temperature: the water it contains will turn to ice at exactly 0.6 °C.

The Ice Maker cools 30kg of Water at a rate of 0,16K/s.

We calculate the delete heat as: SHC * ΔT * Mass : 4,179 (DTU/g)/C * -0,16C * 30kg = 20,06kDTU.

The Ice Maker only produces +16k DTU/s this means we delete 4kDTU/s while it's running.

This can be helpful early game. Especially since the heat can be removed from specific areas easily by moving the ice into the vicinity and it's an easy way to turn duplicant labor into heat deletion.
